We're dividing 606731 by 15 
We're looking to find how many times 15 goes into 606731.

On to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 15

Advancing to step 2:
If we divide 60 by 15, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 60 from 60 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 15

Moving on to step 3:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 6, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 15

Step 4:
15 can be fit into 67 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Subtract 60 from 67 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 15

Moving on to step 5:
The number 15 fits into 73 4 times, leaving a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4044.0
Subtract 60 from 73 to get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 15

On to step 6:
When dividing 131 by 15, we get 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 40448.0
If we subtract 120 from 131, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
15 goes into 110 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 40448.7
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 40448.73
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 40448.733
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 40448.733 with a remainder of 0.0005.
